Postfix mail server — relay control, port toggle, and SpamAssassin integration
New Features
4- Backend Postfix settings applier extended with cPanel-grade controls. Authenticated SMTP relay (allow_external_relay) now toggles permit_sasl_authenticated in smtpd_recipient_restrictions.
- mynetworks is built dynamically from server primary IP plus operator-trusted CIDR ranges.
- Master.cf service blocks for SMTP (25), Submission (587), and SMTPS (465) can now be toggled individually from the panel.
- SpamAssassin content filter integration writes content_filter into main.cf and a managed pipe service block into master.cf, with atomic backup, postfix check validation, and automatic rollback on failure.
